Dell G3 3779 bad PCH or EC?
Hi.
I have a Dell G3 3779 (CAL53 LA-F611P), which had a short on +3VALVP and a partial short on +1.8VALWP (27ohm).
For +3VALWP I found a shorted capacitator, that I swapped with a good one. No more short there.
But for the +1.8VALWP I hope it is not PCH. So, what I did:
I removed solder blob from PJP1802 and determined, that the low 27ohm resistance is on pin 2 (+1.8V_PRIM)
I removed UG12 (AOZ1331DI dual channel load switch), and the resistance on +1.8V_PRIM increased to 167ohm.
So, next ICs on the path is EC and PCH. Could any of those be bad?... -
ASUS G513R - cannot remove MOSFET
Hi.
I have a ASUS G513R laptop with shorted MOSFET (MP86959GMW-Z 45A).
I tried to preheat the board to 200C brom the bottom and with rework station set to 400C I flowed it for about 2min. The MOSFET does not come off.
Of course, I did not force it, but tried to lift it up with tweezers.
Is it possible, that these MOSFETs are glues to the board? Or it got welded to the board from the short? It looks intact, no signs of blowing up.
